ARTHUR MARCUS HILL, OF ST. STEPHEN, NEW BRUNSWICK, CANADA.

GAelNe-ROD.

SPECIFICATION forming part of Letters Patent No. 423,154, dated March11, 18901.

Application filed November l0, 1887. Serial No. 254,749. (No model.)

To @ZZ whom it may concern;

Be it known that I, ARTHUR MARCUS HILL, of St. Stephen, in the Provinceof New Brunswick, Canada, have invented a new and Improved Gaging-Rod,of which the following is a full, clear, and exact description.

The obj ect of my invention is to provide a new and improved gaging-rodfor measuring with great accuracy the cubic contents of kegs, casks,barrels, dac.

The invention consists of certain parts and details and combinations ofthe same, as will be fully described hereinafter, and then pointed outin the claim.

Reference is to be had to the accompanying drawings, forming apart ofthis specification, in which similar letters of reference indicatecorresponding` parts in both figures.

Figure 1 is aside elevation of my improvement as applied. Fig. 2 is aplan view of the same.

My improved gaging-rod consists of two partsthe rod A, provided with theusual graduation, and the dart B, pivotally secured to one end of therod A. The dart B is provided with a straight edge a and aslightlycurved edge b, standing nearly at right angles to the edge a.The pivotal point of the rod A and thedart B is nearly the corner of theintersection of the edges d and h, so that the pointed end of the rod isheld at the angle of intersection of the head and staves of the barrelbeing gaged.

The gaging-rod is used as follows: In measuring kegs, oasks, dac., andcomputing their contents it is only necessary to know the length of thediagonal line from the middle' Y of the bung-hole to the intersectingpoint of one head with the stave opposite the bunghole. Now, it has beenfrequently found that casks, kegs, &c., are marked in excess of theiractual contents by reason of the slot 'or recess at the intersection ofthe head and stave being included as" part of the diagonal when measuredwith the common rod now in use. Vith my improved gaging-rod thisinaccuracy is avoided, as the dart B, when introduced into the barrel byits rod A, as shown in Fig. l, rests with the straight edge ct'againstthe head of 'the barrel, whileV the other curved edge rests on the staveopposite the bunghole, so that the rod A indicates by its graduation theactual length of the diagonal at the bung-hole of the barrel.

The dart B, on account of being pivoted at the end of the rod A, adaptsitself to the various sizes and forms of casks, kegs, doc.

It will be seen that with my improvement I am enabled to measure withgreat accuracy the diagonal of the Cask, and hence can compute thecorrect cubic contents.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A gaging-rod consisting of the graduated rod A and the dart B, providedwith the straight edge a and the slightly-curved edge b, nearly at rightangles to the edge a and pivoted to the end ofthe said rod,substantially as herein shown and described.
